概括
在中国妇女中,体重不足可以防止全身和腰部骨折,而肥胖增加了全身,腰部和股骨部骨折的风险. 身体质量指数 (BMI) 影响骨折风险,可能由骨矿物质密度 (BMD) 介导.
科学领域:
- 骨科和骨健康 骨科和骨健康
- 骨质疏松症的流行病学
- 老年医学 老年医学
背景情况:
- 骨质疏松性骨折在全球人口老龄化中是一个显著而不断升级的健康问题.
- 关于身体质量指数 (BMI) 和骨质疏松性骨折之间的关系的现有研究表明,基于骨折部位和种族的差异性.
- 在中国本土人群中,关于这种关联存在着显著的知识差距,特别是在使用本地参考数据库时.
研究的目的:
- 研究中国妇女不同骨部位的体重指数 (BMI) 和骨质疏松性骨折之间的关联.
- 分析BMI类别 (包括体重不足,正常体重,超重和肥胖) 对骨折风险的影响.
- 探索骨矿物质密度 (BMD) 在BMI-骨折关系中的潜在调解作用.
主要方法:
- 一项病例控制研究,涉及3098名患有放射性骨折的女性患者和3098名年龄和性别匹配的健康对照.
- 骨矿物质密度 (BMD) 的测量是使用双能X射线吸收计 (DXA) 与中国本地BMD参考数据库进行的.
- 根据中国的BMI标准,参与者被分为体重不足 (BMI <18.5 kg/m2),正常体重 (18.523.9 kg/m2),超重 (2427.9 kg/m2) 和肥胖 (BMI ≥28 kg/m2).
主要成果:
- 脊椎骨折是最常见的 (74.1%),其次是大腿 (12.1%) 和其他骨折 (13.8%).
- 与对照组相比,骨折组观察到较低的骨矿物质密度 (BMD) (p = 0.048至 < 0.001).
- 体重不足显示出对全身和腰部骨折 (OR < 1) 的保护作用,而肥胖显著增加了全身,腰部和股骨部骨折 (OR > 1) 的风险. 总体体重指数和骨折之间的J曲线关联在整个部,腰部和大腿部部部位上被注意到.
- 在对骨质量进行调整后,体重不足成为"其他类型"骨折的危险因素 (OR = 2.29). 骨质疏松症和骨质疏松症被确定为大多数骨折部位的重要危险因素.
结论:
- 在中国女性中,体重不足与总体和腰椎骨折的风险降低有关,而肥胖是总体,腰椎和股骨骨折的重要风险因素.
- 观察到的BMI和骨质疏松性骨折之间的关联表明,骨矿物质密度 (BMD) 在调解这种关系方面发挥着至关重要的作用.
- 这些发现突显了中国女性的BMI,BMD和骨折风险之间的复杂相互作用,强调了针对性预防策略的必要性.

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Bone Remodeling
38.3K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Osteoclasts in Bone Remodeling
2.9K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...
